Playing around with simple wire stripper, I added a small visegrip to the screw to act as a depth adjusting handle and it also makes it easy to return over and over to the same setting. The block that I used is a piece of some industrial plastic similar to nylon that was mixed in with scrap metal from a machinery fabricating shop. Thanks again for posting the basic idea. I love it!
